Wibbly-wobbly magnetic fusion stuff: The return of the stellarator

Are Technica describes a new kind of fusion reactor that's coming online. Wibbly-wobbly magnetic fusion stuff: The return of the stellarator "The heliac, the stellarator, and the tokamak are all trying to achieve the same thing: confine a plasma tightly in a magnetic bottle, tightly enough to push protons in close to each other. They all use a more-or-less donut shape, but that more-or-less involves some really important differences. That difference makes the stellarator a pretty special science and engineering challenge." Here's one of the magnets built to hold the field's shape: W7x spule 1440x1920 500
